Abstract We summarize the observational aspects of the transient solar coronal features known as coronal mass ejections. Recognizing the importance of understanding this form of solar activity, particularly in the light of relations to flare and prominence activity, and geomagnetic effects, we consider the spectrum of models which ...

Detection and Tracking of Coronal Mass Ejections
2008Coronal Mass Ejection (CME) events refer to the appearance of a new, discrete, white-light feature (with outward velocity) in a coronagraph. The huge amount of data provided by the pertinent instruments onboard the Solar and Heliospheric Observatory (SOHO) and, most recently, the Solar Terrestrial Relations Observatory (STEREO) makes the human-based ...

Forces governing coronal mass ejections
Advances in Space Research, 2006Kinematics of CMEs is analyzed to get an insight into the properties of forces partaking in the eruption. It is demonstrated that the Lorentz force plays a dominant role within a distance of a few solar radii. In the distance range 1– 30 solar radii, the inferred values of the Lorentz-force acceleration aL on average decrease with the ...

Turbulence in coronal mass ejections
Journal of Geophysical Research: Space Physics, 1997The magnetic fields measured by the ISEE 3 spacecraft are used to study MHD turbulence within coronal mass ejections (CMEs). The spectral indices of the turbulence inside CMEs are compared with spectral indices found in solar wind undisturbed by CMEs. Irrespective of the CME velocities, the spectra within CMEs are found to differ from those determined ...

Geoeffectivity of Coronal Mass Ejections
Space Science Reviews, 2007Coronal mass ejections and post-shock streams driven by them are the most efficient drivers of strong magnetospheric activity, magnetic storms. For this reason there is considerable interest in trying to make reliable forecasts for the effects of CMEs as much in advance as possible. To succeed this requires understanding of all aspects related to CMEs,

Coronal Mass Ejections and Magnetic Helicity
2005Coronal mass ejections (CMEs) are the most energetic events in the solar system, expelling up to 1016 g of coronal material at speeds of several hundreds or thousands of km s−1 from the Sun. As CMEs are the primary cause of space weather disturbances, we need to understand their underlying cause(s) in order to be able to predict them. After an overview
